Abstract

A testing member for eliciting blood samples is provided that can be rotatably mounted inside a cartridge and having a lancet for lancing a body part of a user. The lancet can protrude from an edge of the testing member. The testing member also can have a second blood collection part, and second contact pads, where the second contact pads being electrically connected to the second blood collection part, the second blood collection part and second contact pads together being configured to facilitate an analysis of the quantity of blood in a first blood sample in the second blood collection part. A blood analysis part and first contact pads can be included, where the first contact pads are electrically connected to the blood analysis part, the blood analysis part and first contact pads together being configured to facilitate an analysis of a second blood sample in the blood analysis part.

Claims

1. A blood glucose meter comprising:

a cartridge, the cartridge having an aperture configured to receive a body part of a user; and

a testing member for eliciting blood samples, the testing member configured to be rotatably mounted inside the cartridge, the testing member comprising;

a lancet for lancing a body part of a user, the lancet protruding from an edge of the testing member;

a second blood collection part;

second contact pads, the second contact pads being electrically connected to the second blood collection part, the second blood collection part and second contact pads together being configured to facilitate an analysis of the quantity of blood in a first blood sample in the second blood collection part;

a blood analysis part; and

first contact pads, the first contact pads being electrically connected to the blood analysis part, the blood analysis part and first contact pads together being configured to facilitate an analysis of a second blood sample in the blood analysis part;

the blood glucose meter further comprising a processor and a motor;

wherein the processor causes the testing member to be rotated by the motor such that the blood analysis part and the second blood collection part are able to be presented at an aperture in the cartridge in turn and wherein the processor determines when the amount of blood absorbed into the second blood collection part exceeds a predetermined threshold level and causes the motor to rotate the testing member from the second blood collection part to the blood analysis part only when it is determined that the threshold level is exceeded.

2. A blood glucose meter according to claim 1, wherein the second blood collection part is disposed on a second protrusion of an edge of the testing member.

3. A blood glucose meter according to claim 2, wherein the second blood collection part is disposed at the end of the second protrusion.

4. A blood glucose meter according to claim 2, wherein the second protrusion is impregnated with an antiseptic substance.

5. A blood glucose meter according to claim 4, wherein the antiseptic substance is an antibacterial substance.

6. A blood glucose meter according to claim 1, wherein the blood analysis part is disposed on a first protrusion of an edge of the testing member.

7. A blood glucose meter according to claim 1, wherein the first contact pads are electrically connected to the blood analysis part by first conductive tracks and the second contact pads are electrically connected to the second blood collection part by second conductive tracks that cross the first conductive tracks without electrical connection therebetween.

8. A blood glucose meter according to claim 1, wherein the second contact pads are electrically connected to the second blood collection part by conductive tracks disposed within the body of the testing member and the first contact pads are electrically connected to the blood analysis part by conductive tracks disposed on an upper surface of the body of the testing member.

9. A blood glucose meter according to claim 8, wherein the second contact pads are disposed on a secondary surface of the testing member defined by a step in the thickness of the testing member, the secondary surface being below the level of the upper surface.

10. A blood glucose meter according to claim 1, wherein the blood analysis part contains an enzyme.

11. A blood glucose meter according to claim 1, further comprising a first blood collection part.

12. A blood glucose meter according to claim 11, wherein the blood analysis part and the first blood collection part are integral.

13. A blood glucose meter according to claim 1, wherein the second blood collection part is disposed on a second protrusion of an edge of the testing member, and wherein the second protrusion is configured to contact the body part of the user received in the aperture subsequent to lancing so as to clean the surface of the body part.
